Summary

Include the SunPKCS11 provider in the JDK for 64-bit Windows.

Motivation

More and more vendors are providing native PKCS#11 libraries for 64-bit
Windows. Shipping the SunPKCS11 provider in the JDK for 64-bit Windows will
allow Java applications to use such libraries on that platform.

Description

Modify the current build process to build the SunPKCS11 provider binary on
64-bit Windows. The provider will be placed in the relevant subdirectory but
will not be configured by default. To use the provider, an application would
have to supply its own configuration file that specifies the location of the
native PKCS#11 library along with additional directives according to the
specification in the SunPKCS11 Reference Guide.

Testing

Find a suitable 64-bit PKCS#11 library and run existing regression tests
against it. If the 64-bit library does not support certain functionality
covered by the existing regression tests then some adjustments will be
required.
